Etymology
. A combination of the Latin words: curvus and spina, referring to the epandrium with 1 hooklike spine on anteroventral corner.
Diagnosis
. Epandrium with 1 hook-like spine on anteroventral corner (
Fig. 28
); paramere apically with 1 small sclerotized projection (
Fig. 29
); aedeagal median rod strongly sclerotized, slender on basal half, expanded on distal half (
Fig. 29
); vertical process of gonopods strongly sclerotized, deeply, nearly symmetrically bifurcated from median (
Fig. 29
).
Description
. Male: Eyes brown. Ocellar triangle brown to black. Frons brown on upper 1/2, black on lower 1/2, with thick dense setae medially. Fronto-orbital plate silvery white. Pedicel and first flagellomere almost yellow; arista apically expanded, without ventral branches (
Fig. 27
). Face yellow-brown on upper 1/2, dark brown on lower 1/2. Clypeus medially white-yellow, laterally black. Gena and postgena brown to dark brown. Palpus brown basally, grey-yellow distally. Thorax and scutellum orange-brown, with black patches and pollinose pattern. Legs yellow except for fore femur brownish; fore tarsomere V lacking long setae apically. Abdominal tergites I+II yellow, the rest brown. Sternites III to VI slightly longer than respective width. Male terminalia: Epandrium mid-dorsally constricted, laterally broadened, with dense setae along ventral to posterior margins (
